The present invention is applied to the automatic edit methods of multi-channel video of campus football match.This method is divided into two parts:1) regard Frequency is obtained;2) video is edited automatically.
In video acquisition step, prepare four inexpensive video cameras (such as mobile phone, common camera) first, by video Frame rate is adjusted to 30-60 frames.First cameras is opened and enters video shooting mode, and is shot with four video cameras The stopwatch of same Millisecond.Then camera function is not closed, camera pedestal is set to four angle points in court.Shoot stopwatch Frame of video is in follow-up analysis by the time synchronized for video.In shooting process, the shooting angle of every video camera is all It is fixed.The antenna height of video camera may be selected 2 to 4 meters.
In the automatic editor of video, by automatic decision that all the way video camera can capture football, the road images of Bing Jiang tetra- In the present frame for being set to output result video all the way.
First according to the shooting angle of every video camera, the Football Field Turf range flags in picture are come out, i.e., to drawing Face sets a quadrangle, and quadrangle interior zone is court lawn, and quadrangle perimeter is non-lawn region.
During video acquisition, background estimating is carried out to lawn region in image first.
For N (N=100) frame video image of most start recording, background is initialized as follows:
A) for the pixel of N two field pictures, 3 classes, all pixels system of each class are classified as in the way of C mean clusters The mean μ and standard deviation sigma of its color are counted as central value and excursion, and records the number of pixels Si for belonging to every class background.
B) the differential threshold T of one class center value is set again, if two classes central value Euclidean distance be less than T if Two categories combinations.Therefore at each moment, the background classification of each pixel is up to 3 classes, minimum 1 class.
For the pixel p of newest acquisition, its color value is Color, calculates central point and the immediate background classes of its color Other i.And background is updated according to following three kinds of modes.
If a) be less than 10 with the immediate background i of new pixel current pixel quantity Si, and new pixel color with most Euclidean distance close to the average of background is less than 20, then directly is judged as new pixel to belong to background i.And be added to new pixel Among background i, and Si is led plus 1.If the Si after updating is more than or equal to 10, the central value and standard deviation of the background are counted.This That pixel of record time earliest in the total pixel of background is deleted afterwards, it is ensured that the total pixel number amount of three class backgrounds is N.
If b) the current pixel quantity Si with the immediate background i of new pixel is more than or equal to 10, new pixel is calculated Color Color and background classification i center μiEuclidean distance d (p-i)=| Color- μi|, if d (p-i) is less than background i's 3 times of standard deviation sigmai, then new pixel is added in the category, and update the central point μ of the categoryiAnd standard deviation sigmai.Hereafter delete Except that pixel that the record time in the total pixel of background is earliest, it is ensured that the total pixel number amount of background is N.
If c) being not belonging to two kinds of situations above with the immediate background i of new pixel, then it is assumed that be found that new background. Now, if current background quantity is equal to 3, that minimum background of pixel quantity Si is deleted, and deletion belongs to the background All pixels.After deletion, new background classification is set up with new pixel, background classification central value is the color Color of new pixel, newly The pixel quantity of background is 1, and standard deviation wouldn't be estimated.
During context update, the new pixel occurred in each frame is recorded, the candidate pixel of moving target is used as.For Moving target candidate pixel in each frame, the combination of pixels that all 8 neighborhoods are connected is got up, and constitutes multiple UNICOM's bodies.According to The area of UNICOM's body and the current location that football is judged with round degree of approximation.Further according to the areal calculation current video of UNICOM's body The size of middle moving target.
Time synchronized is carried out according to the stopwatch picture frame for most starting to shoot to thinking video camera, each moment is found corresponding Four road images.
Background modeling and analysis are all carried out to four road images, the moving target UNICOM body in four tunnels is obtained.And according to as follows Mode sets the present frame of video editing result:
Circularity highest UNICOM body in UNICOM's body is found, is demarcated as football.
If only having football in image all the way, then the road image is just set to the present frame in video clipping.
It is if having football in multiway images, then compare the area of football in the picture, football image area is maximum Image be set to present frame.
If have football in multiway images, and its image area difference within 10%, then according in image own The gross area of moving target judges.The bigger image of the moving target gross area is set to video frequency output present frame.
